To clean the intake pressure sensor and oxygen sensor yourself, you can follow these steps::
First, you'll need to prepare some tools and materials, including compressed air, detergent, cotton swabs or soft cloths, protective gloves and masks. Make sure you are able to dispose of these chemicals and detergents safely.
Next, drive the vehicle to a safe place and make sure the engine is cold. This is very important because heat may be generated during the cleaning process, which may damage the engine or other components.
Then, you can start cleaning the intake pressure sensor. First, disconnect the connecting plug from the inlet pressure sensor. Use compressed air to blow off dust and dirt from the sensor. If there is oil or carbon deposits on the surface of the sensor, it can be cleaned with a cleaning agent. However, be careful not to use too strong a cleaning agent to avoid damaging the sensor surface. After cleaning, dry the sensor surface with a clean cotton swab or soft cloth and reattach the plug.
Next is the cleaning of the oxygen sensor. Again, first disconnect the plug from the oxygen sensor. Use compressed air to blow off dust and dirt from the sensor. Oil or carbon deposits on the surface of the oxygen sensor can be cleaned with a cleaning agent. However, be careful not to use too strong a cleaning agent to avoid damaging the sensor surface. After cleaning, dry the sensor surface with a clean cotton swab or soft cloth and reattach the plug.
Finally, you can start the engine and check if the sensors are working properly. If everything is in order, you have successfully cleaned the intake pressure sensor and oxygen sensor.
It is important to note that care should be taken during the cleaning process to avoid damage to the engine or other components. If you're not sure how to proceed or are concerned about possible problems, it's best to have a professional clean and maintain it.
